A modulation transfer function (MTF) graph of an optical image capturingsystem is used to test and evaluate the contrast and sharpness of thegenerated images. The vertical axis of the coordinate system of the MTFgraph represents the contrast transfer rate, of which the value isbetween 0 and 1, and the horizontal axis of the coordinate systemrepresents the spatial frequency, of which the unit is cycles/mm orIp/mm, i.e., line pairs per millimeter. Theoretically, a perfect opticalimage capturing system can present all detailed contrast and every lineof an object in an image. However, the contrast transfer rate of apractical optical image capturing system along a vertical axis thereofwould be less than 1. In addition, peripheral areas in an image wouldhave a poorer realistic effect than a center area thereof has. Thevalues of MTF in a quarter of the spatial frequency at the optical axis,0.3 field of view, and 0.7 field of view on an image plane arerespectively denoted by MTFQ0, MTFQ3, and MTFQ7; the values of MTF inhalf of the spatial frequency (half frequency) at the optical axis, 0.3field of view, and 0.7 field of view on an image plane are respectivelydenoted by MTFH0, MTFH3, and MTFH7; the values of MTF in full frequencyat the optical axis, 0.3 field of view, and 0.7 field of view on theimage plane are respectively denoted by MTF0, MTF3, and MTF7. The threeaforementioned fields of view respectively represent the center, theinner field of view, and the outer field of view of a lens, and,therefore, can be used to evaluate the performance of an optical imagecapturing system. The optical image capturing system provided in thepresent invention mainly corresponds to photosensitive components whichprovide pixels having a size no large than 1.12 micrometer, and,therefore, a quarter of the spatial frequency, a half of the spatialfrequency (half frequency), and the full spatial frequency (fullfrequency) of the MTF diagram are respectively at least 110 cycles/mm,220 cycles/mm and 440 cycles/mm.

If an optical image capturing system is required to be able also toimage for infrared spectrum, e.g., to be used in low-light environments,then the optical image capturing system should be workable inwavelengths of 850 nm or 800 nm. Since the main function for an opticalimage capturing system used in low-light environment is to distinguishthe shape of objects by light and shade, which does not require highresolution, it is appropriate to only use spatial frequency less than110 cycles/mm for evaluating the performance of optical image capturingsystem in the infrared spectrum. When the aforementioned wavelength of850 nm focuses on the image plane, the contrast transfer rates (i.e.,the values of MTF) in spatial frequency of 55 cycles/mm at the opticalaxis, 0.3 field of view, and 0.7 field of view on an image plane arerespectively denoted by MTFI0, MTFI3, and MTFI7. However, infraredwavelengths of 850 nm or 800 nm are far away from the wavelengths ofvisible light; it would be difficult to design an optical imagecapturing system capable of focusing visible and infrared light (i.e.,dual-mode) at the same time and achieving certain performance.

The present invention provides an optical image capturing system, whichis capable of focusing visible and infrared light (i.e., dual-mode) atthe same time and achieving certain performance, wherein the fifth lensthereof is provided with an inflection point at the object-side surfaceor at the image-side surface to adjust the incident angle of each viewfield and modify the ODT and the TDT.

At least one lens between the second lens and the fifthlens has positive refractive power. The optical image capturing systemsatisfies:

1.2≦f/HEP≦6.0; 0.5≦HOS/f≦3.0; 0.2≦EIN/ETL<1;

where f is a focal length of the optical image capturing system; HEP isan entrance pupil diameter of the optical image capturing system; HOS isa distance in parallel with the optical axis between an object-sidesurface, which face the object side, of the first lens and the imageplane; ETL is a distance in parallel with the optical axis between acoordinate point at a height of ½ HEP on the object-side surface of thefirst lens and the image plane; EIN is a distance in parallel with theoptical axis between the coordinate point at the height of ½ HEP on theobject-side surface of the first lens and a coordinate point at a heightof ½ HEP on the image-side surface of the fifth lens.

The present invention further provides an optical image capturingsystem, including a first lens, a second lens, a third lens, a fourthlens, a fifth lens, and an image plane, in order along an optical axisfrom an object side to an image side. The number of the lenses havingrefractive power in the optical image capturing system is five. At leastone lens among the first to the fifth lenses have at least an inflectionpoint on at least one surface thereof. The first lens has negativerefractive power, and the second lens has refractive power. The thirdlens has positive refractive power. The fourth lens has refractivepower.

The optical image capturingsystem satisfies:

1.2≦HEP≦3.0; 0.5≦HOS/f≦3.0; 0.2≦EIN/ETL<1;

where f is a focal length of the optical image capturing system; HEP isan entrance pupil diameter of the optical image capturing system; HOS isa distance in parallel with the optical axis between an object-sidesurface, which face the object side, of the first lens and the imageplane; ETL is a distance in parallel with the optical axis between acoordinate point at a height of ½ HEP on the object-side surface of thefirst lens and the image plane; EIN is a distance in parallel with theoptical axis between the coordinate point at the height of ½ HEP on theobject-side surface of the first lens and a coordinate point at a heightof ½ HEP on the image-side surface of the fifth lens.

For any lens, the thickness at the height of a half of the entrancepupil diameter (HEP) particularly affects the ability of correctingaberration and differences between optical paths of light in differentfields of view of the common region of each field of view of lightwithin the covered range at the height of a half of the entrance pupildiameter (HEP). With greater thickness, the ability to correctaberration is better. However, the difficulty of manufacturing increasesas well. Therefore, the thickness at the height of a half of theentrance pupil diameter (HEP) of any lens has to be controlled. Theratio between the thickness (ETP) at the height of a half of theentrance pupil diameter (HEP) and the thickness (TP) of any lens on theoptical axis (i.e., ETP/TP) has to be particularly controlled. Forexample, the thickness at the height of a half of the entrance pupildiameter (HEP) of the first lens is denoted by ETP1, the thickness atthe height of a half of the entrance pupil diameter (HEP) of the secondlens is denoted by ETP2, and the thickness at the height of a half ofthe entrance pupil diameter (HEP) of any other lens in the optical imagecapturing system is denoted in the same manner. The optical imagecapturing system of the present invention satisfies:

0.3≦SETP/EIN<1;

where SETP is the sum of the aforementioned ETP1 to ETP5.

In order to enhance the ability of correcting aberration and to lowerthe difficulty of manufacturing at the same time, the ratio between thethickness (ETP) at the height of a half of the entrance pupil diameter(HEP) and the thickness (TP) of any lens on the optical axis (i.e.,ETP/TP) has to be particularly controlled. For example, the thickness atthe height of a half of the entrance pupil diameter (HEP) of the firstlens is denoted by ETP1, the thickness of the first lens on the opticalaxis is TP1, and the ratio between these two parameters is ETP1/TP1; thethickness at the height of a half of the entrance pupil diameter (HEP)of the first lens is denoted by ETP2, the thickness of the second lenson the optical axis is TP2, and the ratio between these two parametersis ETP2/TP2. The ratio between the thickness at the height of a half ofthe entrance pupil diameter (HEP) and the thickness of any other lens inthe optical image capturing system is denoted in the same manner. Theoptical image capturing system of the present invention satisfies:

0.2≦ETP/TP≦3.

The horizontal distance between two neighboring lenses at the height ofa half of the entrance pupil diameter (HEP) is denoted by ED, whereinthe aforementioned horizontal distance (ED) is parallel to the opticalaxis of the optical image capturing system, and particularly affects theability of correcting aberration and differences between optical pathsof light in different fields of view of the common region of each fieldof view of light at the height of a half of the entrance pupil diameter(HEP). With longer distance, the ability to correct aberration ispotential to be better. However, the difficulty of manufacturingincreases, and the feasibility of “slightly shorten” the length of theoptical image capturing system is limited as well. Therefore, thehorizontal distance (ED) between two specific neighboring lenses at theheight of a half of the entrance pupil diameter (HEP) has to becontrolled.

In order to enhance the ability of correcting aberration and to lowerthe difficulty of “slightly shorten” the length of the optical imagecapturing system at the same time, the ratio between the horizontaldistance (ED) between two neighboring lenses at the height of a half ofthe entrance pupil diameter (HEP) and the parallel distance (IN) betweenthese two neighboring lens on the optical axis (i.e., ED/IN) has to beparticularly controlled. For example, the horizontal distance betweenthe first lens and the second lens at the height of a half of theentrance pupil diameter (HEP) is denoted by ED12, the horizontaldistance between the first lens and the second lens on the optical axisis denoted by IN12, and the ratio between these two parameters isED12/IN12; the horizontal distance between the second lens and the thirdlens at the height of a half of the entrance pupil diameter (HEP) isdenoted by ED23, the horizontal distance between the second lens and thethird lens on the optical axis is denoted by IN23, and the ratio betweenthese two parameters is ED23/IN23. The ratio between the horizontaldistance between any two neighboring lenses at the height of a half ofthe entrance pupil diameter (HEP) and the horizontal distance betweenthese two neighboring lenses on the optical axis is denoted in the samemanner.

The horizontal distance in parallel with the optical axis between acoordinate point at the height of ½ HEP on the image-side surface of thefifth lens and image surface is denoted by EBL. The horizontal distancein parallel with the optical axis between the point on the image-sidesurface of the fifth lens where the optical axis passes through and theimage plane is denoted by BL. To enhance the ability to correctaberration and to preserve more space for other optical components, theoptical image capturing system of the present invention can satisfy0.2≦EBL/BL≦1. The optical image capturing system can further include afiltering component, which is provided between the fifth lens and theimage plane, wherein the horizontal distance in parallel with theoptical axis between the coordinate point at the height of ½ HEP on theimage-side surface of the fifth lens and the filtering component isdenoted by EIR, and the horizontal distance in parallel with the opticalaxis between the point on the image-side surface of the fifth lens wherethe optical axis passes through and the filtering component is denotedby PIR. The optical image capturing system of the present invention cansatisfy 0.1≦EIR/PIR≦1.

In an embodiment, a height of the optical image capturing system (HOS)can be reduced while |f1|>f5.

In an embodiment, when the lenses satisfy f2|+|f3|+|f4| and |f1|+|f5|,at least one lens among the second to the fourth lenses could have weakpositive refractive power or weak negative refractive power. Herein theweak refractive power means the absolute value of the focal length ofone specific lens is greater than 10. When at least one lens among thesecond to the fourth lenses has weak positive refractive power, it mayshare the positive refractive power of the first lens, and on thecontrary, when at least one lens among the second to the fourth lenseshas weak negative refractive power, it may fine tune and correct theaberration of the system.

In an embodiment, the fifth lens could have negative refractive power,and an image-side surface thereof is concave, it may reduce back focallength and size. Besides, the fifth lens can have at least an inflectionpoint on at least a surface thereof, which may reduce an incident angleof the light of an off-axis field of view and correct the aberration ofthe off-axis field of view.

Sixth Embodiment

As shown in FIG. 6A and FIG. 6B, an optical image capturing system ofthe sixth embodiment of the present invention includes, along an opticalaxis from an object side to an image side, a first lens 610, a secondlens 620, an aperture 600, a third lens 630, a fourth lens 640, a fifthlens 650, an infrared rays filter 680, an image plane 690, and an imagesensor 692. FIG. 6C shows a modulation transformation of the opticalimage capturing system 60 of the sixth embodiment of the presentapplication in visible spectrum, and FIG. 6D shows a modulationtransformation of the optical image capturing system 60 of the sixthembodiment of the present application in infrared spectrum.

The first lens 610 has negative refractive power and is made of plastic.An object-side surface 612, which faces the object side, is a convexaspheric surface, and an image-side surface 614, which faces the imageside, is a concave aspheric surface. The object-side surface 612 and theimage-side surface 614 both have an inflection point.

The second lens 620 has positive refractive power and is made ofplastic. An object-side surface 622 thereof, which faces the objectside, is a convex aspheric surface, and an image-side surface 624thereof, which faces the image side, is a convex aspheric surface. Theobject-side surface 622 has an inflection point.

The third lens 630 has positive refractive power and is made of plastic.An object-side surface 632, which faces the object side, is a convexaspheric surface, and an image-side surface 634, which faces the imageside, is a convex aspheric surface. The object-side surface 632 has aninflection point.

The fourth lens 640 has negative refractive power and is made ofplastic. An object-side surface 642, which faces the object side, is aconcave aspheric surface, and an image-side surface 644, which faces theimage side, is a convex aspheric surface. The image-side surface 644 hasan inflection point. The object-side surface 642 has two inflectionpoints, and the image-side surface 644 has an inflection point.

The fifth lens 650 has positive refractive power and is made of plastic.An object-side surface 652, which faces the object side, is a convexsurface, and an image-side surface 654, which faces the image side, is aconcave surface. The object-side surface 652 has two inflection points,and the image-side surface 654 has an inflection point. It may help toshorten the back focal length to keep small in size. In addition, it mayreduce an incident angle of the light of an off-axis field of view andcorrect the aberration of the off-axis field of view.

The infrared rays filter 680 is made of glass and between the fifth lens650 and the image plane 690. The infrared rays filter 680 gives nocontribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies|f2|+|f3|+|f4|=8.4735 mm; |f1|+|f5|=8.9495 mm; and|f2|+|f3|+|f4|<|f1|+|f5|, where f2 is a focal length of the second lens620, f3 is a focal length of the third lens 630, f4 is a focal length ofthe fourth lens 640, and f5 is a focal length of the fifth lens 650.

In the sixth embodiment, the first lens 610, the third lens 630, and thefourth lenses 640 are positive lenses, and their focal lengths are f1,f3, and f4. The optical image capturing system of the sixth embodimentfurther satisfies ΣPP=11.46338 mm; and f3/ΣPP=0.15626, where ΣPP is asum of the focal lengths of each positive lens. It is helpful to sharethe positive refractive power of the third lens 630 to other positivelenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the sixth embodiment furthersatisfies ΣNP=−5.95967 mm; and f1/ΣNP=0.56425, where ΣNP is a sum of thefocal lengths of each negative lens. It is helpful to share the negativerefractive power of the first lens 610 to the other negative lens toavoid the significant aberration caused by the incident rays.
